This would involve the expansion of tie-in application PlayStation Suite, which is currently only available on two Sony-made tablets and a mobile phone, and more partnering on its Sony Ericsson joint venture.

"This isn't an ecosystem where we want to keep everything within the Sony family," said Sony executive deputy president Kazuo Hirai. "This is not just for Sony devices."

Hirai wouldn't comment on what companies Sony had approached about carrying PlayStation Suite, but the application currently runs on Google's Android platform and individual devices would need to meet certain hardware specifications set by the company.

He would not comment on reports that Sony is in advanced talks to buy out its partner, Ericsson.
